Vapor Intrusion Assessment: Guidelines, Data Collection Methods, & Advancements

The webinar included the following presentations:

Laurent Levy, Jacobs [PDF] After briefly introducing vapor intrusion concepts, the presentation provided a review of current guidelines issued by the U.S. states to address assessment of the vapor intrusion pathway with a focus on TCE, PCE, attenuation factors (in residential/commercial settings), petroleum vapor intrusion, and sampling expectations.

David Shea, Sanborn Head & Associates [PDF] provided an overview of VI pathway assessment methods, from conventional sampling techniques to advancements in data collection, such as real-time field screening, building pressure control, passive sampling, and guided sampling.
